Master Crashes when Slave Connects #474

Closed logan-miles closed 3 years ago

logan-miles commented 8 years ago

Starting two instances on different servers. Both are initially set as master with nothing connecting them, and they run fine. When I set one instance to be slave of the other, the master crashes. I have run the memory test and confirmed that it's not a bad memory issue. This is the log from the master:

Hi @wewereschizo since 2.8.2104 there has been several fixes and code improvements, you should upgrade to the latest release 2.8.2402. Thank you.
